Key points of planting techniques of Tiannanxing

Artemisia angustifolia is a traditional Chinese medicine with a long history of cultivation in China, which has the effects of detoxification and detumescence, resolving phlegm and dispelling wind. It is often used in the treatment of nerve paralysis, hemiplegia, infantile typhoid, tetanus and other diseases. And the scope of planting in China has also been very wandering, basically dealing with the northwest and Xizang areas, lower than all parts of the planting. So how to cultivate high-yield and high-quality Tiannanxing? Let's take a look at the technical points of planting Tiannanxing brought by the editor.

1. Seed treatment

The seed treatment of Artemisia angustifolia plays a very important role in its planting process, which basically determines the survival rate, yield and quality. So first of all, we need to divide the seed stem of Artemisia angustifolia into three grades: large, medium and small, and then soak the seeds with methyl topiramate mixed with appropriate amount of carbendazim and avermectin, and the soaking time needs to be determined according to the size of the stem, 24 hours, 12 hours and 12 hours respectively. Finally, remove the soaked stems and store them in a cool, ventilated place. Keep the temperature at 5 to 7 degrees, turn it over every half a month, and wait until early spring to sow seeds.

2. Planting time

The sowing time of Tiannanxing can be in early spring, but it can also be sown if the winter temperature is not below minus three degrees Celsius. The time of sowing is usually from November to December in late autumn, but it is best to sow in spring. Generally, spring sowing can be carried out when the low temperature is above 8 degrees Celsius.

3. Planting method

The methods of planting Tiannanxing include seed propagation and stem propagation, but the growth period of seeds is very long, and the yield is not high, so the most commonly used is stem propagation. Before planting, it is necessary to select the soil suitable for planting in the south, and to prepare the soil and apply sufficient basic fertilizer; the second is to carry out soil treatment and disinfection; and finally to sow. When sowing, the seeds and stems of different grades should be planted separately. Large species are generally planted according to the spacing of 25 rows and 15 centimeters between plants; the spacing between rows of middle species is generally 20 and the spacing between plants is 10 centimeters; the spacing between rows of races is the same as that of middle species, but the spacing between plants is generally five centimeters.

4. Field management

Field management is the top priority in the planting technology of Tiannanxing. In the early stage of emergence and after emergence, it should be properly watered, and soil cultivation and weeding should be carried out. In the middle and later stage of growth, it is necessary to reduce the soil moisture properly to prevent the plant from rotting. Secondly, it is best to interplant, so that appropriate shading management can be carried out, of course, if the temperature is high, physical cooling is needed. When the seedlings grow to about 18 centimeters, the first topdressing is irrigated with feces and urine, and the second topdressing is in the middle of the growth of Tiannanxing, which is applied with phosphorus and potassium fertilizer in loose soil ditches. Finally, when the Buddha flame bracts grow out, it should be removed in time, so that several nutrients can be made to promote the growth of tubers.

The most important thing of Tiannanxing planting technology is to understand the growth habits of Tiannanxing, the second is to master the planting technology, and reasonable use of professional knowledge to achieve maximum economic benefits. These are the key points of planting techniques of Tiannanxing that the editor would like to share with you today. I hope I can help you to plant.
